Flywheel-type systems, also known as flywheel energy storage systems, are mechanical devices designed to store rotational energy for later use. They consist of a massive flywheel, typically made of materials with high strength-to-weight ratios such as composite materials or high-strength steel, mounted on a central shaft. The flywheel is spun up to high speeds using an electric motor, and the energy is stored as kinetic energy. When energy is needed, the flywheel's rotational speed is reduced, and the kinetic energy is converted back into electrical energy using a generator.

Flywheel-type systems are valued for their high power density, rapid response times, and long cycle life. They can provide power in milliseconds, making them suitable for applications requiring quick energy release, such as regenerative braking in electric vehicles or grid stabilization. Their cycle life can exceed one million cycles, making them a durable and reliable energy storage solution.

However, flywheel-type systems also have limitations. They have relatively low energy density compared to other storage technologies like batteries. Additionally, they require precise control systems to manage the flywheel's speed and prevent overspinning or stalling. Despite these challenges, ongoing research and development aim to improve their energy density and efficiency, making flywheel-type systems an increasingly attractive option for various energy storage applications.
